▎ 摘　　要

NOVELTY - High-temperature resistant and oxidation-resistant graphite plugging agent comprises 30-40 pts. wt. nano graphene powder, 15-20 pts. wt. magnesium chloride, 15-20 pts. wt. manganese chloride, 5-15 pts. wt. sodium phosphate, 80-85 pts. wt. phosphoric acid, and 15-20 pts. wt. anhydrous alcohol. USE - The high temperature resistant and oxidation resistant graphite plugging agent is useful for plugging the opening in the traditional isostatic pressing graphite after plugging. ADVANTAGE - The high temperature-resistant oxidation-resistant graphite plugging agent has excellent oxidation resistance and high temperature resistance, and is environmentally friendly, low toxicity, and does not require processing as adhesive. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation method of high-temperature resistant and oxidation-resistant graphite plugging agent.
